Aircraft lock

Abstract

The invention relates to a lock ( 100 ) comprising: -two substantially planar walls ( 101 ) bearing a first pivot connection axle ( 102 ) and a second pivot connection axle ( 103 ), the first and second axles being substantially perpendicular to the planes; -a catch ( 108 ) able to pivot about the first axle, the catch comprising a hook ( 109 ) able to catch a strike wire; -a pawl ( 111 ) able to pivot about the second axle, the pawl comprising a tooth ( 112 ) able to engage with at least one notch ( 113, 114 ) formed on the catch, when the lock is in what is known as the closed position; -a control lever ( 115 ) able to pivot about the second axle, the lever comprising a means ( 116 ) of driving the rotation of the pawl ( 111 ) about the second axle, the control lever comprising means ( 118, 119 ) for securing the closure of the lock.

1 . A lock comprising:
 two substantially planar walls bearing a first pivoting link axis and a second pivoting link axis, the first and second axes being substantially perpendicular to the planar walls;   a catch capable of pivoting about the first axis, said catch comprising a hook capable of receiving a keeper;   a pawl capable of pivoting about the second axis, said pawl comprising a tooth capable of engaging with at least one notch formed on the catch;   a control lever capable of pivoting about the second axis, the lever comprising a means for driving the pawl rotationally about the second axis; and   said lock being characterized in that the control lever comprises means for securing closure of the lock, said securing means comprising a hook formed on the control lever and a lug disposed on the catch, substantially parallel to the first axis.   
     
     
         2 . The lock as claimed in  claim 1 , characterized in that the hook cooperates with the lug when the lock is in the closed position. 
     
     
         3 . The lock as claimed in  claim 2 , characterized in that the control lever and the pawl are situated between the planes of the walls. 
     
     
         4 . The lock as claimed in  claim 1 , characterized in that the means of driving the pawl rotationally is a shoulder capable of cooperating with at least one lug formed on the pawl. 
     
     
         5 . The lock as claimed in  claim 1 , characterized in that the control lever and the pawl are configured as one piece. 
     
     
         6 . The lock has claimed in  claim 1 , comprising means for detecting a position of the pawl. 
     
     
         7 . The lock as claimed in  claim 6 , characterized in that the means for detecting the position of the pawl comprise a visual marking disposed at one end of the control lever. 
     
     
         8 . The lock has claimed in  claim 6 , characterized in that the means for detecting the position of the pawl comprise an inductive sensor. 
     
     
         9 . The lock as claimed in  claim 1 , characterized in that the walls additionally bear a third axis and a fourth axis substantially parallel to the first axis, the lock being capable of being fixed to a panel by means of the first, the third and the fourth axes. 
     
     
         10 . The lock as claimed in  claim 1 , characterized in that the control lever and the pawl are situated between the planes of the walls.
